How Plagiarism Detection Actually Works
Modern detection is more than a simple keyword search. It's how universities find copied content. Here is how we analyze your document.
Text Segmentation
We break your document into small segments or word sequences. We then search for each segment across our massive database.
Database Comparison
We match every segment against 70+ billion sources. This includes websites, journals, books, and student papers. Our matching happens in real time.
Semantic Analysis & Scoring
We also find paraphrased text and synonym swaps. You get a clear similarity score and a report that links every match to its original source.
What Gets Flagged
Detection tools identify multiple categories of academic dishonesty, not just copy-paste plagiarism.
Verbatim Copying
This is word-for-word copying. Even one sentence without quotation marks can trigger a flag in professional university tools.
Paraphrased Content
This is text that was reworded but not cited. We find these matches even if you change the words but keep the ideas.
Mosaic & Patchwork
This is blending phrases from many sources. We check your whole document at once to find fragments from different places.
Translated Plagiarism
This is translating content without credit. We check your English text against German, French, Spanish, and other sources.
Self plagiarism
This is reusing your own past work. Most universities treat recycling your own papers as a serious integrity violation.
AI-Generated Content
Our Combo Check also finds text from ChatGPT, Claude, and other AI models. This is now a top concern for schools.
Understanding False Positives
Not every highlight in your report is plagiarism. We flag similarity, not intent. You can use your report to check every finding yourself.
Highlights often include quotes, lists of references, and standard academic phrases. These are not usually problems if cited correctly.

Plagiarism Detection, Frequently Asked Questions
We split your document into small segments. Then we compare them to billions of web pages and journals. If a segment matches, we flag it. We also use smart analysis to find paraphrasing, not just exact matches.
Universities often use Turnitin or PlagAware. Over 11 German universities use PlagAware. We use that same technology. This means you can check your work with the tool your school uses.
Yes. Properly quoted text, bibliography entries, common academic phrases, and standard template language may all be flagged. These are not actual plagiarism. That is exactly why the report provides direct links to every matched source, you can verify each finding yourself and determine whether it represents a real problem.
Yes. Advanced detection including PlagAware uses semantic analysis to identify paraphrased content even when no exact words match. If you take someone else's ideas and rephrase them without attribution, the system can identify the likely source and flag it as a potential paraphrase rather than a direct copy.
First, run our plagiarism check to identify all flagged passages. For each flagged section: add a proper in-text citation if the content is correctly referenced but missing one; rewrite the passage in your own words and add a citation; or format directly quoted text as a block quotation. Properly cited material should not be penalized during your university's own review.
